题目
题型:不详难度:来源:
We can eat in the dining hall. But we _______ eat in the classroom.
A.don’tB.didn’tC.can’tD.aren’t

答案
C
解析

试题分析:句意:我们可以在餐厅吃饭,但是我们不能在教室吃饭。can’t不能够,情态动词的固定用法,结合句意,故选C
点评:情态动词用法较多,无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。 must必须肯定的推测,can’t表否定的推测。个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去,现在或将来。中学阶段必须对它们的用法有个基本的了解,题目不难,掌握了平时出现的题目即可答出。
